SPECIFICATION forming part of Letters Patent No. 789,443, dated May 9, 1905.

Application filed July 2l, 1904. Serial No. 217,523.

Beit known that 1, ALBERT D. Moons, a citizen of the United States of America, residing at South Hadley Falls. in the county of .Hampshire and State of Massachusetts, have invented new and useful Imprm'ements in Shuttle-Boxes for Looms, of which the following is a specification.

This invention relates to looms, and has special reference to the construction of shuttleboxes, the object of the invention being to construct a shuttle-box of sheet metal, whereby the box may be more cheaply made and the ,lurability thereof greatly increased, the method of construction permitting' certain parts thereof, which are subjected to the greatest wear, to be made of metal which can be hardened and tempered before the box is put together.

In the drawings accompanying' this specification a shuttle-box is shown provided with two compartments only; but it is obvious that the construction maybe arranged to comprise as many as are required for the work.

Heretofore shuttle-boxes have generally been made of cast metal, usually cast-iron rendered malleable in the well-known manner. These boxes, owing' to the nature of the construction, have their interior surfaces all linished off with a lile, owing to the fact that the shape of said surfaces renders a machine-iinish impracticable. This method of finishing greatly enhances the cost of the boxes. Furthermore, shuttle-boxes as heretofore made of cast metal are a source of constant annoyance and expense, owing' to the constant breakage, usually at the mouth of the box, necessi tating the stopping of the loom to supply a new box or to repair the broken one. Furthermore, a box may run for sometime before the break is discovered, to the great injury of the shuttle, which becomes badly abraded by coming in contact with the broken edges of the box, and, as is well known, this roughened surface of the shuttle is the cause of much breakage of the threads of which the fabric is made.

By means of the present invention a shuttlebox is made much more cheaply and the interior surfaces iinished much more perfectly,

as all of the parts may be made of bright stock, and the piece forming` the mouth of the shuttle which is subjected to the greatest amountof wear may be hardened, all of which results in great economy in the use of a box made according to this invention as compared with the cast-iron or malleable-iron boxes new in use.

1n the drawings forming part of this application, Figure l is a perspective view of a shuttle-box in its complete form constructed according to this invention, the binders being omitted. Fig. 2 is a longitudinal sectional plan view in the plane of line 2 2, Fig. 1. Fig. 3 is a transverse sectional view in the plane of line 3 3, Fig. l. Fig. 4 is a view showing in perspective the component parts of the shuttle-box in separated relation.

Referring to the drawings, if and I) indicate, respectively, the top and bottom plates of the box, each of which in its complete form is shown in Fig. a, both being' identical in shape. The lower edge of each of these plates is turned inward at right angles to thcplane of the body thereof, forming the flange c. The mouth of the shuttle-box, to which one end of the plates t and are secured, is made of two pieces, (shown in their separated relation in Fig. 4,) one of these pieces forming the front and the other the back side of the monthpiece. The latter consists of a fiat metal plate (l, having at or near each corner thereof and formed integrally therewith an upstanding leg f1, .7", 17, and the front plate j being provided with two legs and m, located centrally of the two sides of the plate integral therewith, and they are of such width that they will lit closely, one between the legs a and /r and the other between the legs f/ and f, when the parts are applied one to the other, as shown in Fig. 1. The stock of which these plates di and j are made is of the same thickness, to the end that when the two parts are put together in the manner shown in Fig. l thc legs /L and e of one plate and of the other will constitute a continuous side surface for the mouthpiece and the similarly-located legs on the other side of said plates alike surface. It will be noted that the ends of the legs /L and (j will fit into the notches o and p, cut in the IOO side of the plate ZZ, and the end of the leg's c and f of the plate Z will fit into similar notches f' and s in the opposite side of the plate j. ln the ends of the legs t and f a rectangular notch t is cut, whose depth is equal to the thickness of the plate y', said notches forming a shoulder on which the rear end of said plate may rest.

The flanges c on the top and bottom plates t and Z2 terminate at the rear edge of the plate (Z, and that part of said plates beyond the end of the flange extends into the mouthpiece of the shuttle-box and is provided with holes, as e, which register with holes fw in the legs of the plate (Z and in the legs of the plate j, whereby the plates a and Z may be riveted securely to the mouthpiece and whereby the ends of said plates which lie within themouthpiece constitute a binding-plate for the two parts of the mouthpiece.

wWhen the legs on the plates Z and fare bent up at right angles thereto, the bend is formed in such manner that the plane of the inner surface of the legs will be located outside the plane of the edge of the plate a distance substantially equal to the thickness of the plates a and Z), and on the lower edge of the plates a projection fr is formed, which will lit in between the edge of the plate Z and the inner surface of the ends ofthe legs and m. of the plate j. This constitutes a lock for the plates and takes much of the shearing strain off the rivets.

The forward edge of the plate j is outwardly curved, as indicated at y, whereby the mouthpiece is given the usual flare on this side, to the end that should the shuttle vary slightly in its flight it will be properly directed into the box. The forward edge of the plate ZZ is preferably reinforced by means of a strip 3, which is riveted thereto on the under side, said piece extending across the front edge of the plate, which is thereby doubled in thickness, and after being so riveted to said edge the latter is ground off to a rounded form in crosssection to prevent any injury to the shuttle on entering the box.

At the rear end of the shuttle-box the top and bottom plates are secured together by a front plate only, lettered 4, having rectangularlyarranged integral sides 5, the distance between which is the same as the distance between the legs and m. The rear ends of the top and bottom plates u and Z) are located inside of the sides 5 of the plate 4, the end of each of the plates having a tongue 6 thereon which enters slots 7 in the upper surface of the plate 4, the sides 5 and the ends of the plates (z and Z) being' riveted together. On the forward end of each of the top and bottom plates are the tongues 8 and 9, the latter extending far enough above the surface of the plate j to constitute, together with the piece 10 in the center of the plate j, suitable supports for the rod, (not shown,) which extends from one side of the shuttle-box to the other over the ends of the shuttle-binders, whereby the outward movement of the latter may be limited. ,lt will be observed that notches o, `r, p, and s, formed in the plate y', are deep enough to receive the tongues 8 and 9 on the plates (Z and Z), as well as the legs of the plate (Z, and still leave the outer surface of the latter flush with the sides of the legs and m. The rear ends of the usual shuttlebinders (not shown) may be supported on a rod carried in the ears 1Q on the plate 4, the latter being cut away, as at 14, between the ears l2 to permit that end of the shuttlebinder to swing freely on its hinge. Toward the rear end of the plate 4 ribs l5 are struck up on the surface of the plate substantially in line with each of the ears 1'2 and are made to receive between them the end of a fiat shuttle-binder spring, a screw entering the hole 16 to secure said spring' to the plate 4. This construction may be the same as in ordinary shuttle-boxes. There the tongues 6 project through the slots 7, they may be made long enough to be headed over on the plate, if desired,

The foregoing description is that of the construction of the shuttle-box proper, and the box may be subdivided into as many longitudinal compartments as the nature of the work to which it is to be adapted requires. By the introduction between the plates a and of one or more partitions 20, having a suitable flange 2l extending along' the bottom edge thereof, (said partitions being parallel with the plates a and and said flange being' in the same plane as the flanges 0,) a shuttle-box adapted to carry any desired number of shuttles may be provided. These partitions may be made and are preferably made, as shown in Fig. 4 particularly, of a `sheet of metal which when bent upon itself will substantially equal in thickness the plates a and L, and in bending the two thicknesses of metal together the rib Q1 may be formed along' the lower edge thereof in the well-known manner by leaving' the rib-forming portion tubular and then shutting it up in a pair of dies to form the flange at right angles to the body of the partition.

That end of the partition which divides the mouthpiece to form a compartment on each side thereof is provided with tongues 24, which enter slots 25, punched through both the plates Z and j, as shown in Fig. 4, the ends of these tongues being' headed over on said plates to secure the partitions firmly thereto. Similar tongues 26 are formed on the rear ends of the partition, but only on one side thereof, contiguous to the plate 4, and which enter the slots 28 in said plate, the tongues being headed over on the plate.

The rear edge of the plate CZ has recesses 30 cut therein to provide space for the proper l throw of the picker.

IOO

veaeas 1t is clear from the foregoing description that a box constructed in the manner described will have all of the characteristics ofthe shuttle-box now in vogue as far as the shape thereof is concerned, the manner of supporting' the box, and the manner of applying' the shuttlebinders.

If the ends of the shuttle-binders which lie on the plate y' are narrower than the space between the project-ions 9 and l0, a block 3l may be applied to the inner surface of the projections 9 and riveted thereto,` whereby said space may be reduced to substantially the width of the ends of the binders.
